Localization associations are mainly centered around companies.

"The Localisation Research Centre (LRC) is the information, educational, and research centre for the localisation industry."

SLIG has become the representative body for the localization industry in Ireland. It is made up of Industry Partners, State Agencies, Colleges and Universities, and Research Institutes.

"Its mission is to enable companies to succeed in international markets by providing focused training for professionals and by promoting the sharing of experience and information among them […] The Localization Institute is best known for its annual Localization Managers Roundtable, a gathering of localization leaders from around the globe."

LISA defines its mission as "promoting the localization and internationalization industry and providing a mechanism and services to enable companies to exchange and share information on the development of processes, tools, technologies and business models connected with localization, internationalization and related topics".

The mission of PAL is to provide its members with structured education and training; standardization and best practices; information about translation trends, tools, and career opportunities; discussion forums; and representation in the fields of Localization, Internationalization and Globalization. PAL intends to serve and represent those who prepare software and documentation for the world. To support its member translators, localizers, internationalizers, and globalizers, PAL assembles and provides information, organizes professional events, and serves as an advocate for member concerns.
